| Abstract | The degradation of the bonding of the tile-wall structure has emerged as an urgent issue in metropolitan cities, with more and more tile-dropping accidents caused. In order to ascertain the bonding integrity of tile-walls, impact acoustics features obtained from the sound signals generated by controlled impact are employed to develop a rapid and effective nondestructive inspection technique. To facilitate the automatic interpretation, the multilayer artificial neural network (ANN) is used as a cost-effective classifier superior to traditional statistics methods. Nonetheless, the classical gradient descent based backpropagation (BP) training strategy of the multilayer neural network faces certain drawbacks, e.g., very slow convergence, easily getting stuck in a local minimum. In this paper, an evolutionary algorithm based training method is developed to train the ANN and perform the automatic classification of bonding integrity. The design, feature extraction approach, training and application of the proposed evolutionary neural network are presented. The classification results obtained experimentally from prepared sample slabs are presented and compared with that with BP algorithm, demonstrating the validity of the proposed methodology. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
